Hello,

I am thinking to setup a new PBS server or a 3 node proxmox with CEPH/NFS to act as our PBS needs locally. Anyone has build any high performance PBS server so in the event of restoration it can be super quick?

Would you mind to share your spec?
 
Hello kellogs, a solution depends on your given SW+HW constrains you set, your volume of vm sizes (... TB) and installed network bandwidth.
A "3 node proxmox with CEPH/NFS to act as our PBS" wouldn't anyway "super quick".
1st restore instance is snapshot like, 2nd local streaming images, 3rd remote streaming, 4th remote deduplicated images, ... , tape.
Smaller to bigger ones would go different approaches to solution.

Hello waltar,

I could go with dual 100G and Enteprise NVME disks for the PBS, maybe that is the fastest money could get ... i wonder if there is any delay/tuning on the PBS so it allows large number concurrent restoration assuming both disk and networks are the best out there.

Hello @waltar - if possible, could you elaborate or point to documentation in regards of the mentioned "1st, 2nd, 3rd ..."? Very interesting. @kellogs i really like your approach. I prefer this much more than elaborated error-intensive (many point of failures) HA-setups. / "RTO Zero for VMs is a myth" ;) anyhow.

Hello FrankList80, as written it depends how the backup system is defined in location, type (disk/tape), and backup volume.
If you want go fast maybe don't think about PBS anymore, eg if you think about a disk based backup with nvme's and you are a zfs fan
making vm image backups in new zfs 2.3 dedup+compressed datasets with date based structure export this to pve servers and restore images over nfs mount - depend on image usage on pve with "local" dd or cp cmd. If you have really big backup volume because of many big vm's and many states bacula could be your friend. A most efficient and fast backup/restore solution isn't integrated in pve webui but that's just a little bit another way to do both (backup+estore).

Thank you for this insights. A lot to investigate. Thanks.
